The use of heap allocated GMutex/GCond is deprecated. Instead place them
inside the structure they are locking.
These changes switch to use g_mutex_init/g_cond_init rather than the heap
allocation functions.
Because we cannot test for a NULL pointer for the GMutex/GCond we must
initialise inside the GObject _init function and clear inside the _finalize
which is guaranteed to only be called once and after the object is no longer
in use.
Don't care of the return value for gst_vaapi_decoder_put_buffer()
during destruction of the element. Don't print out (uninitialised)
error code when allocation of video buffer failed.
Reset, i.e. destroy then create, the decoder in _setcaps() handler only
if the underlying codec type actually changed. This makes it possible
to be more tolerant with certain MPEG-2 streams that get parsed to
form caps that are compatible with the previous state but minor changes
to "codec-data".
Add new gst_vaapi_codec_from_caps() helper to determine codec type from
the specified caps. Don't globally expose this function since this is
really trivial and only used in the vaapidecode element.
Previously, vaapidecode would wait up to one second until a free surface
is available, or it aborts decoding. Now, vaapidecode waits until the
last decoded surface was to be presented, plus one second. Besides, end
times are now expressed relative to the monotonic clock.
When playback stops the GstVaapiDecode object is reset into a clean
state. However, surfaces may still be referenced by library users and
unreferencing them after the reset triggers an access to an unset mutex.

Forward declaring enums is not allowed by the C standard and aborts
compilation if the header file is included in a C++ project.

If either dimension is out-of-bounds, then scale window to fit the
display size, even if the output is to be rotated. Use the standard
gst_video_sink_center_rect() function to center and scale the window
wrt. the outer (display) bounds.
Keep VA surface proxy associated with the surface that is currently
being displayed. This makes sure that surface is not released back
to the pool of surfaces free to use for decoding. This is necessary
with VA driver implementations that support rendering to an overlay
pipe. Otherwise, there could be cases where we are decoding into a
surface that is being displayed, hence some flickering.
This is not useful in practice but for raw performance evaluation when
the sink is invoked with display=drm sync=false. fakesink could also be
used though.
If vaapisink is in the GStreamer pipeline, then we shall allocate a
unique GstVaapiDisplay and propagate it upstream. i.e. subsequent
queries from vaapidecode shall get a valid answer from vaapisink.
Move display types from gstvaapipluginutil.* to gstvaapidisplay.* so that
we could simplify characterization of a GstVaapiDisplay. Also rename "auto"
type to "any", and add a "display-type" attribute.
vaapisink is now built with support for multiple display types, whenever
they are enabled. The new "display" attribute is used to select a particular
renderer.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
GStreamer -base plugins >= 0.10.31 are now required, so the checks for
new APIs like GstXOverlay::set_window_handle() and ::set_render_rectangle()
are no longer necessary.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
Bump GStreamer plugins -base required version to 0.10.31, needed for
gst_x_overlay_got_window_handle().

Try to gracefully abort when the HW does not support the requested
profile. There is no fallback unless profiles are correctly parsed
and matched through caps beforehand.
Don't forcibly resize foreign X windows. The user is responsible for
their size and vaapisink shall not change this.
